CRYSTAL STRUCTURE OF C-T-C-T-C-G-A-G-A-G: IMPLICATIONS FOR THE STRUCTURE OF THE HOLLIDAY JUNCTION
Overview
The structure of the B-DNA decamer of sequence C-T-C-T-C-G-A-G-A-G shows a, crossed arrangement of helices in the C2 crystal lattice. This is the, fourth example of a crossed arrangement of B-DNA oligomers in a crystal, and in spite of the fact that each of these four crystallizes in a, different lattice, all have nearly identical structures at the crossing, contact. This ubiquitous crossing arrangement may be used to generate a, structure for the Holliday junction that is fully consistent with the, available physical data.
About this Structure
196D is a Protein complex structure of sequences from [1] with CA as ligand. Full crystallographic information is available from OCA.
